Rendering
You should be happy with the look of your composite now, but you have a ways to go. To
be safe, however, let's render a version of the Nuke tree to disk now. Rendering means to

Using the Write node
To render your tree, you need to use a Write node, which contains several functions. The
Write node defines which part of the tree to render, where to render to, how to call your
file or files, and what type of file you want to create. You're now going to add a Write
nodeattheendofyourtree.Theendofyourtreeiswhereyoucanseethefinalcomposite.
In this case, it's Merge1.
1. Click Merge1 at the bottom of the tree and press the W key. You can also choose
Write from the Image toolbox in the Nodes Toolbar or use the Tab key to create a
Write node by starting to type the word write ( FIGURE 2.32 ) .
